Definitions
- the invention relates to refills for writing, drawing and / or painting implements based on thermoplastic binders, as well as a method for their production.
- thermoplastic binders for drawing, writing and / or painting are known in principle.
- a lead is known from DE 102008034014 A1 which contains at least thermoplastic binders, wax and fillers.
- the binder used is polystyrene, styrene-acrylonitrile, styrene-budadiene, polyolefins and acrylonitrile-budadiene-styrene.
- mines designed in this way are not designed so that they can be painted with water / watercolors and are built on petroleum-based raw materials.
- mines are known from the prior art which are constructed and manufactured on the basis of cellulose derivatives, these derivatives serving as binders.
- cellulose derivatives these derivatives serving as binders.
- a first step raw mines are pressed with the addition of water.
- these raw leads have to be dried in order to obtain a ready-to-use lead.
- the object of the invention is therefore to create a lead for writing, drawing and / or painting that does not have the disadvantages mentioned.
- the object is to create a lead, designed as a graphite and / or colored lead, which is built up on the basis of cellulose and, in particular, can be processed or produced thermoplastically and which is designed to be water-soluble / water-colored.
- a further object of the invention is to produce a mine inexpensively with as little effort as possible, in particular few work steps.
- This object was achieved by creating a lead composition which has hydroxypropyl cellulose (HPC) as a binding agent.
- HPC hydroxypropyl cellulose
- leads constructed in this way can be produced in one work step and are also designed to be watercolourable.
- a lead was created for writing, drawing and / or painting implements, at least comprising at least one binding agent, at least one wax, at least one colorant and at least one filler, the lead being in the form of a lead and / or colored pencil lead, the at least one binding agent is present as hydroxypropyl cellulose (HPC) and the hydroxypropyl cellulose content is 7 to 45% by weight.
- HPC hydroxypropyl cellulose
- the proportion of the at least one binder in the form of HPC in the lead composition is in the range from 7 to 45% by weight, preferably in a range from 10 to 35% by weight.
- FIPC is a derivative of cellulose and is soluble in both water and organic solvents.
- FIPC is thermoplastic.
- FIPC has been used as a pharmaceutical excipient, as a binder for ceramic compounds, coatings for adhesives, in cosmetic articles, in printing inks and in polymerization technology.
- binder 2 0 to 30% by weight
- binder 2 0 to 30% by weight
- the at least one filler is advantageously a mineral filler. Fillers from the groups comprising graphite, hexagonal boron nitride, kaolin, sheet silicates, talc, chalk, barite, colored pigments and / or achromatic pigments may be mentioned as examples.
- graphite or graphite in combination with carbon black is preferred as a filler or as a coloring filler.
- colorless fillers such as hexagonal boron nitride, phyllosilicates, etc.
- coloring pigments such as azo pigments, phthalocyanines, dioxazines, quinacridones, iron oxides, carbon black, graphite, ultramarine, iron-cyan complexes
- the binder 2 polyvinyl alcohol, polyethylene glycol and / or polyvinyl butyral may be mentioned by way of example.
- a composition for a water-soluble pencil lead comprises;
- binder 2 0 to 30% by weight
- Example recipe for a pencil lead includes:
- a composition for a colored pencil lead includes:
- binder 2 0 to 28% by weight of binder 2
- Example recipe for a colored pencil lead
- Colored and / or achromatic pigments can be used as coloring agents for colored leads.
- examples of such pigments are azo pigments, phthalocyanines, dioxazines, quinacridones, iron oxides, carbon black, graphite, ultramarine and iron-cyan complexes.
- At least one wax from the group comprising fatty acids, stearates, montan waxes, amide waxes and paraffins can be used as the at least one wax.
- oils used can be in the form of palm oil, palm kernel oil and / or soybean oil, for example.
- Surfactants can be EO / PO block polymers, ethoxylated alcohols and / or alkyl polyglycosides.
- the extrusion process has proven itself as a process for producing a lead according to the invention.
- the mine according to the invention is produced in particular by performing the following steps:
- the lead cross-section can take any shape - round, angular or combinations thereof. It is also possible to combine different lead recipes in one extrusion head to form a multi-component lead via multiple coextrusion.
- the lead granulate can be extruded into a complete stick using suitable coextrusion processes with other polymer-bound materials.
